The performance of different boundary-layer bleed systems of a two-dimensional ramjet inlet has been investigated experimentally. The main objective of the study has been to identify the boundary-layer bleed geometry that increases the inlet’s performance and to stabilize the subcritical condition (i.e., later buzzing). Experiments have therefore been carried out with varied boundary-layer bleed geometries at an angle of attack of 0 deg and at Mach numbers ranging from 2.5 to 3.5. The results show that the effectiveness of a boundary-layer bleed system depends on shock, boundary-layer interaction, unsteadiness of the flow, and flow separation.
